Rejecting Connections When the Battery is Low

My application will use a rechargeable battery.  I will let it run down to 2V or so before I need to reject connections until it charges back up.  I can continue advertising because that has some value and does not effect charging much.

   

 

   

My battery voltage is measured by an external microcontroller which can set a pin on the BLE IC or it can send a command via I2C.

   

 

   

How can I reject BLE connections during "run time"?  Can I read the "no conection signal" via I2C and then disallow connections?

   

 

   

Thanks

Perhaps use the on chip ADC to measure it's own supply voltage to reject connection attempts?
